TO ALL WHOM IT MAY CONCERN:

Boe it known that we, .learns ,BINGHAM and'RonEn'r Allegheny, and State of Pennsylvania, havc'invented a new and useful i Combined Rock-Crusher and Tempering- Machine, for crushing and tempering clay-rock for 'the manufacture o'f brick, earthenware pipe, or toany of the uses clay is put to; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being hadrto the accompanying drawings, and to thelettersnof'reference marked thereon.

The nature of our invention consists iny providing a substantial frame, on thetop of which'two housings,

through which, in suitable bearings, two corrugated or fluted rollers revolve, below which are two smooth-faced rollers, of two different diameters, whichalso pass through and rotateY through the' heretofore-mentioned housings, by also providing, below these smooth-t`aced rollers, a chute or spout, the extremity of which rest-s on the frame before mentioned, and the other end is above a large deep dish orbasin, which 'we term a sludge-pan, and

the said sludge-pan is supported by a hollow annular cylinder, with an aperture at the base. This cylinder' Arests-upennI be lplate,which-is the foundation Aof the frame heretofore mentioned. By furnish-ing; also, six4 geared wheels, which act as the movers ofthe rolls heretofore mentioned, viz, one gear-wheel attached to a inain horizontal driving-shaft, on the end of which is axcd a driving-pulley or drum, which gear-wheel drives a counter horizontal shaft by reason of another gear-wheel upon it, on the end of which horizontal counter-shaft -is attached a bevel-gear wheel, which is rotated bythe counter-shaft in suitable bearings, and by also furnishing another bevel-gear wheel of the same pitch as the bevel-gear wheel before mentioned,` whichis ailixed to a vertical shaft, which passes through the before-described sludge-pan and annular'hollow cylinder, and rcvolvesin a suitable bearing or step beneath the annulareylinder.l Y

4To this vertical shaft lare attachedthrec or more sets of knives or beaters, placed at` rightA angles to each other, and bent 'in such a form that their outside edge or line "will -be of an Archimcdian-screw form; and these knives or beaters, being attached to the vertical shaft, yrevolve with it within the annular cylinder.

By also providing a spider, consisting of four or more arms, with two orzmore sets of knives or beaters attached to eacjh arm, which spider` is furthermore attached to the aforesaid vertical shaft, in such a manner and in such a position, that as the vertical shaftrevolvcs, the knives will nearly touch the bottom of the sludge-pan. These knives are of such a form, and set at such an angle, that they would have'the tendency in their circular travel te force anything within the sludgc-panto the centre thereof. By also providing a gear-wheelon the mainhorizontal shaft` and attached to one of the smooth-faced rollers before described, in such a manner that thisA gear-wheel will mesh Vor interlacc its teeth with another gearlwheel of the same pitch, which is ailixed to one of the corrugated or luted lrollers before described.` By also providing, on the opposite side of the 'corrugated roller, a geared pinion. By also providing, on the same side of the other corrugated roller, another geared pinion of the same pitch as the pinion just described, both so arranged th'atthe-teethef the respective pinion's will mesh or interlace. By also providing a geared pinion upon oneof thelower smooth rollers,.and on'the opposite side than that which has the driving-gear wheel before mentioned; and by also providing, on the same side, ageared pinion to the other smooth roller, bothpinions being Yso arrangedthat their respective teeth or cogs will mesh or interlaec. By also providing a cross-frame, stretching between and at the top of the beforementioned housings. .This c rosssframe hasv anvaperture of anoval form. Y To enable, others skilled in the art of constructing machinery to'm'ake and use our invention, we willproceed to describe its construction and operation'.

step, in which the vertical shaft V'rotates.,

We `propose making 'the roller L oflarger diameter than the roller K, since the pinions T T, on the ends of the respective smooth rolls, being of the same diameter and'piteh, would revolve the rollers equally as regards speedf, By giving a larger diameter to the roller L, ithas a tendency to attenuate or draw out whatever material passes through.-

AThe operation of Workingpour combined rock-Crusher and tempering-machine is as follows, viz Motion is communicated to all the movable pats'by applying steam or horsefpower to the maindrivingwheel, thewhole-being so combined, arranged, and put together, that when the' clay, rock, or any other such like material, may be thrown through the aperture I' of th cross-frame H of the housings Gr, the rock falls on the top of the corrugated rolls J and J, and by their revolving 'the rock is crushed, and 'passesthrough to the top of the smooth rolls K and L, by whose action the material is thoroughly pulvcrized or granulated,'andl falls through on thc-chute M, bylwhieh it-is conveyed into the sludge-pan X, and is subjected to the rotary motion and the knives-Z make and at the same time the knives are forcing the paste down into the annularcylinder, and it'is furthermore subjected to the action of the knives B, which force the pastethrough the aperture C" ofthe eylinder'At.

The advantage we claim in our combined rock-crusheigand tempering-machine, is, simple, and so is not likely to be easily disarranged, and also that it will, with ease, convertit into mud, of any required consistency for the manufacture lof brick, or any other such like article,

that the machine is so such as pipe gas-retorts.

We also #contemplate using ou:` machine for crushing coppeibor iron ore, or flint or quartz rock. Having thus described the nature, construction, and operation of our combined rock-Crusher and tempering- The two pairs of rollers J and JJ and K L', the spout-M, the sludge-pan X, the spider Y, having knives Z, the-annular cylinder AP, and their operative mechanisms, when constructed, combined, and arranged as described, and to operate in'the manner substantially as set forth. i

In testimony whereof, we have signed our names to this specification in the presence of the subscribing Witnesses.
